| 摘要 |
The present invention relates to the field of microwave transitions between a microstrip and a waveguide. With the intention of obtaining a broadband and trimming-free junction, the junction is comprised of a pad which has an underside and an upper side located on respective sides of a tongue that extends into the waveguide. The underside is in contact with the upper side through the medium of a metal layer applied to the edge of the tongue. The upper side is, in turn, connected to the microstrip line which extends to other electronic equipment. Because the two sides can be adapted for different frequencies, the junction can be given a broader band and will also be trimming-free, since it is insensitive to mechanical tolerances. |
